Specification of Letters Patent.

CARTON.

Patented June 3, 1919.

Application led January 13, 1917. Serial No. 142,133.

T0 all whom zz may concern.' v

Be it known that I, HENRY FURs'rE, aciti- Zen of the United States of America, and resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented a new .and useful Improvement in Cartons,

of which the following is a specification.

rllhis invention relates to an improved card board or heavy paper carton and has for an object to produce a carton adapted to seal the interior thereof .against admission of air and light in a more effective manner than other cartons heretofore used and known to me.

A further object is to produce a card board or heavy paper carton of the side opening type in which the free edges of the construction are reinforced to prevent tearing of the material thereof or collapse of the carton and in which 'the various portions ymay be folded and locked in their folded positions without straining or bending the material thereof.

llhese and other objects are attained in the construction described in the following specification and illustrated in the accompanying drawings, in which:

Figure 1 is a perspective view of a carton or box embodying my invention, the lid being shown partly raised.

Fig. 2 is a plan view ofa carton or heavy paper blank from which .a box embodying my invention may be constructed.

F ig. 3 is a plan View of the boxfolded.

vFig. 4 is an end elevation of the box.

Fig. 5 is an end elevation of the box with certain of the flaps unfolded to disclose other folded iaps.

Eig. 6 is a fragmenrtal elevation taken on the line 6-6 of F ig. 4.

Fig. 7 is a transverse sectional view taken on the line 7-7 of Fig. 3.

Fig. 8 is an end elevation showing the position of the top of the box and certain of the otherv elements in the closing operation.

My improved carton is made of a sheet of card board or heavy paper cut to form a blank of the shape disclosed in Fig. 2, in which 'two portions 8 and 9 of the blank are shown folded on the other portions thereof. In this blank, portion 10 forms the front of theA box and portions 11, 12 and 13 respectively form the bottom, back and top of the box. Attached to top portion 13 is a portion 14 adapted to form an auxiliary front. Attached to the end edges of respective portions 11, 12 and 1() are flaps 15, 1G and 17. These flaps when folded form the ends of the box. Attached to the end edges of portions 13 and 14 are respective flaps 18 and 19, these flaps also cooperating with flaps 15, 16 and 17 when t-he lid and auxiliary front of the box are folded to cl-ose the box. Flaps 16 are provided with slits 20 adapted to receive tongues 21 formed on Vi'aps 17. These 'tongues 21 are distinguished from the main portions of flaps 17 by notches 22, t'he purpose of which will be hereinafter more fully described.

The formation of aps 18 and 19 permits of their being moved readily to their folded positions with relation to the body of the box because of the curved edges thereof, edges 23 of flaps 18 being out to the arc of the circle formed with a radius extending from the back corner to the corresponding front corner of the box, and edges 24 of flaps 19 being curved to substantially the radius of the arc drawn from the point of connection of portion 14 with the lid or top of the box, to the edge of portion 14. rlhe remaining edges 25 of flaps 19 are curved so as to facilitate the movement o-f flap 14 with rela-tion to top 13 of the box when they are being moved to their folded positions, the object of so forming edges 25 being to permit porti-on 14 to be folded at a sufficient angle with relation to portion 13, that the bottom edge of portion 14 will clear the top edge of the frontwithout having to spring the material thereof in closing the box. In preparing the blank for folding, the portions and flaps are preferably distinguished from one another by means of scoring which facilitates their being bent or folded in constructing the box. Portions 8 and 9 are folded with relation to portions 10 and 14 and are preferably attached thereto by gluing them in Jche positions disclosed in Fig. 2. The blank is now ready for use.

The first operation is to fold portions 10, 11 and 12 at right angles to one another to form the body of the box, then to fold flaps 15 upwardly from the bottom portion 11 to meet the end edges of portions 10 and 12. I? laps 16 are then bent at right angles to portion 12 and against the outer faces of flaps 15. Flaps 17 are now bent at right angles to portion 10 and are brought to ensov gage the outer faces of liaps 16. Tongues 21 of flaps 17 are now passed through slits of fiaps 16, and notches 2:2 are brought into engagement with the lower ends of slits 2O of {ia-ps 16. rI'he ends of the body portion of the box having thus been constructed, portion 14: is bent at right angles to portion 13 and portion 13 is bent at right angles to box portion 12, flaps 19 and 18 being bent upwardly from the blank as disclosed in Fig. 2, to stand at right angles to portions 14 and 13. The box is now closed by locating iiaps 19 within flaps 18 and then passing flaps 18 within iaps 15, 16 and 17 which have previously been folded to form the ends of the body of the box.

In my improved construction it will be seen that I have produced a carton which is particularly adapted to contain articles which must be kept away from the deteriorating influences of light and air, such as rubber and similar articles.

In addition to this .I have provided a construction in which the free edges are materially reinforced and strengthened by reason of the folding of portions 8 and 9 with relation to portions 10 and 141, thereby avoiding the usual raw edges found in other box constructions. Not only are these edges reinforced, but the top or lid possesses no raw edges and owing to the presence of iiaps 18 and 19, dust and other elements as objectionable as light and air, are also excluded from the contents of the box.

A further feature of improvement lies also in the hook-like construction of the tongues 21 formed on iaps 17, for the purpose of engaging vslits 2O of aps 16, this construction positively locking the body portion of the box and preventing the portions becoming unfolded.

What I claim is: Y,

A carton blank comprising a series of portions adapted to be folded to form the body of a carton, portions attached to the body forming portions adapted to be folded to close the body, flaps attached to certain of the first and second mentioned portions adapted'to be folded into engagement with said certain portions to form reinforced edges, flaps attached to the end edges of the body-forming portions adapted to be folded to form the ends of the body, certain of the iaps being attached to the front and backforming portions, the iaps attached to the back-forming portion having a diagonally extending slit formed thereinjndjacent to its attached edge, the flap attached to the frontforming portion having a hooked tongue formed on the edge opposite its attached edge for locking cooperation with the slit when the flaps are folded, and flaps attached to the end edges of the body-closing portions, having curved edges adapted to facilitate closing of the box without distortion of the material thereof and to reinforce and close the ends of the carton when the body-closing portions are moved to closed position.

In testimony whereof, I have hereunto subscribed my name this 11th day of J anuary, 1917.
